INTERNATIONAL    FEED     GRINDERS 


^ 


Three  Types  of  International  Feed  Grinders 


International  feed  grinders  are  built  in  three  types,  each  type  in  different  sizes,  so  they  may 
meet  all  requirements. 

Type  B  is  designed  primarily  for  grinding  corn  on  the  cob;  it  is  built  in  three  sizes,  with  6,  8 
and  10-inch  grinding  plates. 

Type  C  grinds  small  grain  only — wheat,  barley,  oats,  shelled  corn,  etc.;  it  is  an  efficient,  high-speed 
mill  for  rapid  grinding  of  small  grain.     It  is  built  in  two  sizes,  with  6  and  8-inch  grinding  plates. 

Type  D  is  designed  primarily  for  grinding  corn  in  the  husk.  It  is  built  with  a  spiral  cutter  and 
8  and  10-inch  grinding  plates.

*  It  is  next  to  impossible  to  make  any  definite  statement  regarding  the  capacity  of  a  feed  grinder.  Four  continually  varying 
factors  enter  into  the  computation  of  the  capacity  of  any  feed  grinder.  The  approximate  capacities  of  International  feed  grind- 
ers range  from  5  to  50  bushels  per  hour,  depending  entirely  on  the  condition  of  the  grain,  the  fineness  to  which  it  is  ground,  the  power 
used,  and  the  speed  at  which  the  machine  is  run. 

To  secure  the  greatest  capacity,  these  machines  should  be  driven  at  a  maximum  speed.  Minimum  speed  for  8  and  10-inch 
grinders  is  300  revolutions  per  minute.  Maximum  speed  when  a  flywheel  is  used  is  600  revolutions  per  minute.  At  a  speed  above 
BOO  revolutions  per  minute  the  flywheel  should  be  removed. 

The  following  table  indicates  the  speed  of  International  feed  grinders  equipped  with  different 
size  pulleys  and  operated  with  an  International  oil  engine  from  2  to  20-horse  power.

International  Type  B  Feed  Grinder 


6-Inch  Grinding  Plates 


This  grinder  is  specially 
designed  for  grinding  corn  on 
the  cob.  When  the  supple- 
mentary bottom,  described  on 
page  8,  is  used,  small  grain 
can  be  ground.  The  grinding 
plates  are  6  inches  in  diameter. 
Fine  and  medium  plates  are 
regularly  furnished,  but  when 
specially  ordered,  coarse  and 
extra  fine  plates  can  be  fur- 
nished at  an  additional  cost. 
This  grinder  can  be  operated 
with  from  2  to  5-horse  power, 
at  a  speed  of  125  revolutions 
per  minute  for  each  horse 
power.  The  best  results  will 
be  obtained  when  the  speed  is 
not  less  than  300  revolutions 
per  minute.  At  this  speed, 
under  favorable  conditions,  the 
capacity  is  about  ten  bushels 
per  hour.  At  a  slight  addi- 
tional cost  a  heavy  flywheel 
will  be  furnished  with  this 
grinder.  The  flywheel  should 
be  removed  for  any  speed  over 
600  revolutions  per  minute.

International  Type  B  Feed  Grinder 


10-Inch  Grinding  Plates 


This  grinder  differs  from 
the  6  and  8-inch  grinders  in 
that  the  frame  and  hopper  are 
longer  and  the  main  shaft  is 
larger  in  diameter.  It  is  de- 
signed to  grind  corn  on  the 
cob.  Where  a  large  size  grinder 
is  required,  as  with  feed-store 
men,  stockmen  and  dairymen, 
this  is  a  popular  machine.  The 
grinding  plate,  supplementary 
bottom,  and  flywheel  equip- 
ment is  the  same  for  this 
grinder  as  for  the  6  and  8- inch 
grinders.  The  grinding  plates 
are  10  inches  in  diameter.  The 
supplementary  bottom  and  fly- 
wheel will  be  furnished  when 
specially  ordered  at  an  addi- 
tional cost.  This  grinder  can 
be  operated  with  from  8  to  15- 
horse  power  at  a  speed  of  35 
to  40  revolutions  per  minute 

for  each  horse  power.    The  best  results  will  be  obtained  at  a  speed  of  from  350  to  500  revolutions 
per  minute.    For  a  speed  over  600  revolutions  per  minute,  the   flywheel  should  be  removed.

The  breakers  on  Type  B  feed  grinders  mash  up  the  cobs  and  force  the  grain  toward  the  grinding 
plates  They  are  located  on  the  steel  shaft,  and  to  insure  lasting  qualities  their  points  are  chilled. 
Above  are  shown  the  different  styles  of  breakers  for  the  three  sizes  of  Type  B  grinders. 

Type  B  6,  8  and  10-inch  grinders  can  be 
supplied  with  any  of  the  above  combinations  in 
place  of  the  regular  cob  breaker. 


Grinding  Plate  Shield  and  Hopper  Removed 
to  Show  the  Working  Parts  of  the  Grinder 


Plate  Shifter  Lever 

A  lever  conveniently  located  at  the  end  of  the  shaft 
makes  it  possible  to  separate  the  plates  without  readjusting 
the  tension  spring.  This  is  a  safe-guard  against  breakage, 
because  if  a  stone  or  a  nut  should  get  into  the  mill,  by  one 
quick  movement  of  the  lever,  damage  can  be  avoided.  Also, 
the  plates  may  be  cleaned  without  making  the  tension-spring 
adjustment,  which  is  slow  and  difficult  to  get  to  the  same 
fineness  as  before. 


Plate  Shifter  Lever  and  Tension  Spring 


Spring  Tension 

A  heavy  spring  holds  the  grinding 
plates  in  position,  and  minimizes  the 
danger  of  breakage,  should  any  hard 
substance  get  into  the  grain  by  mistake.  The  pressure  exerted  by  this  spring 
can  be  made  greater  or  less  by  turning  the  thumb  nut  which  holds  the  spring 
in  place.     In  this  way  the  grinder  may  be  regulated  for  fine  or  coarse  grinding. 

Self-Aligning  Grinding  Plates 

A  heavy  steel  shaft,  which  runs  in  extra  long,  anti-friction  babbitt  bear- 
ings, drives  the  crushing  and  grinding  parts  of  the  machine.  The  stationary 
grinding  plate  is  bolted  to  the  frame  of  the  mill;  the  running  plate  is  attached 
to  the  shaft  by  means  of  a  ball  and  socket  connection  shown  in  the  illustration 
on  this  page.  This  connection  permits  the  running  plate  to  keep  in  perfect 
alignment  with  the  plate  on  the  frame  at  all  times;  the  result  is  a  mill  that 
runs  smoothly  and  grinds  evenly. 

The  end  thrust  of  the  shaft  is  taken  up  by  a  ball  bearing.  This  con- 
struction reduces  the  friction  produced  by  the  end  pressure  to  a  minimum.

The  chilled  concave  is  located  be- 
low the  breakers,  and  is  fastened  to 
both  sides  of  the  frame  with  wooden 
pins  on  8  and  10-inch  grinders.  On 
6-inch  grinders  metal  pins  are  used, 
because  where  small  horse  power  is 
employed  the  driving  belt  will  slip  off 
the  pulley  as  soon  as  the  plates  become 
clogged. 


The  Chilled  Concave 


Chilled  Concave  Under  Grinding  Plates 


Large  Steel  Hopper 

The  hopper  is  made  of  sheet  steel,  the  surface  of  which  is  perfectly  smooth.  To  prevent  its 
being  battered  or  bent  out  of  shape  it  is  strongly  reinforced  around  the  top  by  turning  the  outer 
rim  completely  around  an  iron  rod. 


INTERNATIONAL    FEED     GRINDERS 


Grinding  Plates 


International  Type  B  feed  grinders  are  regu- 
larly equipped  with  one  pair  of  fine  grinding  plates 
and  one  pair  of  medium  grinding  plates.  Coarse 
and  extra  fine  plates  can  be  supplied  at  an  addi- 
tional cost.  These  plates  are  made  of  steel  and 
are  not  interchangeable,  as  is  seen  in  the  illustra- 
tion on  this  page,  because  the  stationary  plate 
and  the  running  plate  are  of  different  design. 


Running  Plate 


Stationary  Plate 


Supplementary 


Shut-Off 

A  shut-off  regulates  the  flow  of  grain  into 
the  plates,  and  is  controlled  by  a  small  lever  just 
above  these  plates.  When  closed,  the  shut-oft 
prevents  the  entrance  of  any  grain  to  the  plates. 
This  feature  makes  it  possible  to  regulate  the 
flow  of  grain  to  the  amount  of  power  used. 

Supplementary  Bottom 

Small  grain  may  be  ground  in  all  Type  B 
feed  grinders  when  the  supplementary  bottom 
attachment  is  used.  This  attachment  is  made 
of  sheet  steel  and  is  perfectly  smooth  so  it  will 
not  obstruct  the  grain. 

It  is  put  into  the  hopper  with  the  convexed  surface  fitting  up  close  to  the  opening  which  leads 
to  the  grinding  plates,  forming  a  tube  through  which  small  grain  will  be  forced.    The  flat  surface  is 

inclined  toward  the  grinding  plates  and  is 
fastened  to  the  hopper  by  two  bolts  at  the 
upper  end  of  the  incline.  This  attachment  is 
made  in  three  sizes  to  fit  6,  8  or  10-inch 
grinders. 

Steel  Frame  and  Lag  Screws 

A  strong,  rigid  steel  frame  and  two  lag 
screws  make  it  easy  to  keep  the  mill  in  proper 
relation  to  the  power  used  to  drive  it.  The  lag 
screws  fasten  into  the  floor  and  clamp  over  the 
top  of  the  wooden  braces.  The  clamps  may  be 
loosened  by  turning  a  nut  on  the  top  of  the  lag 
screw.  The  mill  may  be  moved,  in  order  to 
tighten  or  loosen  the  belt,  without  moving  the 
lag  screws,  by  simply  loosening  the  clamps, 
sliding  the  mill  in  the  desired  direction  and  then 

Supplementary  Bottom         Place  i.    Hopper  tightening  them  Up  again.

The  best  results  are  often  obtained  by  feeding  a 
mixture  of  different  grains.  The  most  satisfactory  way 
to  mix  grains  so  that  the  mixture  is  thorough  and  even 
is  by  grinding  them  together.  Small  grain  and  ear  corn 
will  not  mix  thoroughly  or  grind  evenly  when  placed  in 
the  same  hopper.  For  this  reason  a  supplementary 
hopper  is  made  for  6,  8  and  10-inch  Type  B  feed 
grinders  for  grinding  oats  or  other  small  grain,  together 
with  ear  corn.  This  device  consists  of  a  separate  sheet 
steel  hopper  that  sits  above  and  in  front  of  the  regular 
hopper  and  is  clamped  to  the  regular  hopper.  It  is  well 
made,  the  separate  pieces  being  riveted  together,  and 
the  top  reinforced  by  turning  the  outer  rim  around  an 
iron  rod.  The  bot- 
tom slopes  toward 
a  feed  opening 
equipped  with  a 
shut-off.  The  small 
grain  is  put  into  the 
supplementary 
hopper  and  the  ear  corn  into  the  regular  hopper.  The  flow  of 
small  grain  may  be  controlled  by  the  shut-off  lever.  This  attach- 
ment is  furnished  only  on  special  order  at  an  additional  cost.  Supplementary  Hopper 

Advantages  of  Grinding  Feed  with  an  I  H  C  Feed  Grinder 

Grinding  grain  adds  a  great  deal  to  its  value  as  a  feed  for  all  kinds  of  stock.  When  whole  grain 
is  fed,  a  large  part  of  it  is  wasted,  because  it  is  not  thoroughly  masticated  or  digested.  At  the  pre- 
vailing high  market  prices  of  corn  and  other 
grains,  no  one  can  afford  to  waste  any,  however 
small  the  amount  may  be.  When  ground  grain 
is  fed  it  will  be  found  that  as  much  as  35  per 
cent  can  be  saved.  For  animals  out  of  condition 
or  old  animals,  ground  grain  is  essential  if  the 
best  results  would  be  attained.  It  has  been 
thoroughly  demonstrated  in  one  of  the  leading 
experiment  stations  of  the  country  that  one 
pound  of  corn  and  cob  meal  has  the  same  feed- 
ing value  as  one  pound  of  corn  meal.  This 
proves  conclusively  that  it  pays  to  grind  corn

Description  of  Type  C  Feed  Grinders 


Grinding  Plates 

All  running  or  stationary 
grinding  plates  on  the  Type  C 
feed  grinders  are  alike.  All 
Type  C  grinders  are  regularly 
furnished  with  fine  and 
medium  grinding  plates. 


Fine  Stationary  Plate 


Worm  Feed 


Fine  Running  Plate 


Type  C  feed  grinders  are  made  with  a  worm  feed  just  below  the  shut-off.  This  worm  feed 
forces  the  grain  into  the  grinding  plates.  This  feature  is  responsible  for  the  steady  flow  of  grain 
to  the  grinding  plates,  which  is  so  necessary  to  insure  even  grinding.

Hopper  and  Shut-Off 

The  hopper  is  made  of  sheet  steel  and 
is  thoroughly  reinforced  around  the  top ;  the 
outer  rim  is  turned  completely  around  an 
iron  rod.  It  cannot  become  bent  or  knocked 
out  of  shape.  The  inside  of  the  hopper 
is  perfectly  smooth  with  no  projections  to 
obstruct  the  flow  of  grain.  The  bottom 
inclines  toward  the  opening  just  above  the 
worm  feed.  One  excellent  point  in  the 
construction  of  this  mill  is  the  shut-off 
shown  in  the  two  illustrations  on  this  page. 
By  means  of  it  the  flow  of  grain  fed  to  the 
grinding  plates  may  be  shut  down  or  regu- 
lated so  that  an  8- inch  grinder  may  be 
operated  with  an  engine  as  low  as  4-horse 
power.  The  6-inch  grinder  may  be  regu- 
lated to  run  on  as  low  as  2-horse  power. 
When  the  shut-off  is  closed,  no  grain  can 
get  into  the  grinding  plates. 


Steel  Frame  and  Lag  Screws 

A  strong,  rigid  steel  frame  and  two  lag 
screws  keep  the  machines  from  wobbling, 
and  hold  them  firmly  in  position  on  the 
floor.  The  lag  screws  fasten  into  the  floor 
and  clamp  over  the  tops  of  the  wooden 
braces.  The  clamps  may  be  loosened  with- 
out loosening  the  lag  screws,  and  permit 
a  movement  of  eight  inches,  making  it 
easy  to  line  up  the  grinder  with  the  power 
used  to  drive  it.

International  Type  D  Feed  Grinder 


8  and    10-Inch  Grinding  Plates,  Spiral  Cutter 


I 


International  Type  D  Feed  Grinder,  8  and  10-Inch 


This  grinder  is 
primarily  designed  for 
grinding  corn  in  the  husk. 

The  capacities  of 
Type  D  grinders  vary 
widely  with  the  amount 
of  power  used,  the  condi- 
tion of  the  grain,  and  the 
fineness  to  which  the 
grain  is  ground. 

The  8 -inch  grinder 
can  be  operated  with 
from  6  to  10-horse  power, 
at  a  speed  of  100  revolu- 
tions per  minute  for  each 
horsepower.  The  10-inch 
grinder  can  be  operated 
with  from  8  to  15-horse 
power  at  a  speed  of  75 
revolutions  per  minute 
for  each  horse  power.  All 
Type  D  feed  grinders  are 
equipped  with  fine  and 
coarse  grinding  plates.

Gears 

The  cut  below  shows  the  arrangement  of  the  gears  on  the  Type  D  feed  grinder.  The  nature 
of  the  work  done  by  this  machine  requires  a  slow,  powerful  cutting  and  grinding  mechanism. 
By  nesting  three  gears  and  three  pinions  in  the  proper  manner,  the  power  required  to  cut  the 
husks  and  break  the  cobs  is  reduced  to  a  minimum.  The  inside  gear  which  drives  the  shaft 
revolves  but  once  to  every  seven  revolutions  of  the  pulley;  this  increases  the  efficiency  of  the 
cutters  about  33 1 1  per  cent,  and  permits  them,  on  a  slow-running  shaft,  to  cut  up  the  corn  with 
less  engine  power  than  would  be  possible  on  a  fast  one. 

The  machine  is  so  geared  that  one  cutter  knife  revolves  faster  than  the  other,  and  consequently 
it  is  impossible  for  a  big  ear  of  corn  to  wedge  and  stop  the  machine. 

The  gearing  is  completely  covered  to  prevent  injury  to  the  operator,  or  cutting  of  the  gears 
through  the  entrance  of  dust  and  grit. 

Strong  Stand  Construction 

The  machine  is  constructed  with  a  steel  stand  which  stays  where  it  is  put  and  holds  the 
grinder  firm  and  rigid.  The  angle  irons  lag  to  the  floor  and  are  firmly  cross-braced  at  both  ends 
of  the  machine  so  there  is  no  way  for  the  belt  to  get  out  of  line  or  the  machine  to  become  shaky. 

Outer  Shaft  Support 

The  shaft  on  the  Type  D  grinder  runs  out  several  inches  beyond  the  pulley  into  a  long,  anti- 
friction bearing.  The  shaft  is  prevented  from  bending  or  springing,  and  friction  is  reduced  by  an 
outer  shaft  support  shown  in  the  illustration  below.  Because  of  this  support,  none  of  the  working 
parts  of  this  machine  can  be  thrown  out  of  alignment.

Cutter  Bar 


A  noteworthy  feature  of  this  machine  is  the  cutter  bar.  This  is  a  rectangular  bar  running 
parallel  to  the  cutter  knives  and  located  just  below  and  midway  between  the  two.  As  the  knives 
revolve  they  come  in  contact  with  the  edges  of  the  bar;  and  in  this  way  form  a  cutting  surface. 
The  bar  can  be  adjusted  by  set  screws,  either  up  or  down,  or  in  either  direction  sideways.  The 
value  of  this  arrangement  is  readily  seen.  Suppose  that  a  knife,  after  the  machine  had  been  in 
use  some  time,  became  dull,  was  removed  and  ground.  When  replaced,  it  might  not  be  in  proper 
relation  to  the  cutter  bar.  To  get  the  correct  cutting  surface,  the  bar  has  only  to  be  adjusted 
sideways,  up  or  down,  as  the  need  may  require.  If  the  corners  become  worn,  a  new  cutting  surface 
is  supplied  by  simply  turning  the  bar  over. 

Safety  Device 

To  prevent  the  knives  from  breaking,  a 
wooden  break  pin  is  used  to  fasten  the  first 
pinion  to  the  drive  shaft.  Before  any  damage 
can  be  done  by  obstructions  getting  into  the 
cutter,  this  pin  will  give  way. 

Complete  Shut -Off 

The  feed  opening  is  around  the  end  of  the  Pair  of  Fine  G"ndi-s  PIates 

worm.    A  double  slide  shut-off  regulates  the 

amount  of  material  fed  into  the  grinding  plates.     When  closed,  it  prevents  the  admission  of  any 
grain  to  the  plates.    It  can  be  adjusted  to  the  amount  of  power  used. 


Extra  Equipment 

Wagon  Elevator 

The  elevator  illustrated  on  this  page  is  of  great  value  where 
it  is  desirable  to  have  the  ground  feed  placed  in  a  wagon  or 
bin,  as  it  delivers  the  feed  direct  without  handling.  This 
elevator  can  also  be  used  as  a  sacker,  when  the  sacking  attach- 
ment is  substituted  for  the  wagon  spout.  The  wagon  spout 
works  in  a  swivel  and  can  be  adjusted  to  deliver  ground 
feed  in  any  direction.  These  two  attachments  are  inter- 
changeable, and  either  can  be  supplied  with  this  elevator. 
The  wagon  spout  is  regularly  shipped  with  the  elevator. 
The  sacking  attachment  is  supplied  at  an  additional  cost  and 
only  when  ordered.

Extra  Equipment— Continued 
Flywheel 

A  large,  heavy  flywheel  is  furnished  with  all  size  Type  B  feed  grinders  at  an  additional  cost. 
When  the  grinders  are  driven  at  a  speed  above  800  revolutions  per  minute,  the  flywheel  should  be 
removed. 

Sacking  Elevator 

When  it  is  desired  to  sack  ground  feed,  it  is  convenient  to  have  a  sacking  elevator  in  con- 
nection with  the  grinder.  An  efficient  and  well-made  elevator  can  be  had  with  an  I  H  C  feed 
grinder  at  an  additional  cost.  This  elevator  can  be  attached  to  either  side  of  the  machine  in  a 
moment.  When  attached  as  shown  in  the  illustration  on  page  4,  the  belt  should  be  crossed;  when 
attached  to  the  other  side  of  the  machine  the  belt  should  be  straight. 

The  Most  Adaptable  Power 

Oil  and  gas  engines  furnish  by  far  the  most 
adaptable  and  economical  power  for  the  modern 
farm.  These  engines  can  be  operated  on  gas, 
gasoline,  benzine,  naphtha,  kerosene,  solar  oil,  or 
alcohol.  The  power  they  generate  is  practical, 
not  only  for  work  in  the  field,  but  also  for  the 
smaller  jobs  around  the  house,  workshop  and 
barn.  They  furnish  the  most  convenient  power 
for  operating  the  feed  grinder,  and  are  especially 
adaptable  for  this  purpose  on  account  of  the 
variation  in  the  power  required  in  proportion  to 
the  kind  and  condition  of  the  grain  being  ground. 
No  matter  how  much  power  a  feed  grinder  needs 
to  do  its  work  properly,  there  is  an  I  H  C  oil  or 
gas  engine  that  will  supply  it  at  such  a  low  cost 
that  grinding  with  an  International  feed  grinder  operated  by  one  of  these  engines  is  most  profitable. 

I  H  C  engines  are  very  easy  to  operate,  and  when  once  started  require  no  attention  except  for 
an  occasional  oiling. 

The  I  H  C  Line  Includes 

I  H  C  vertical  engines,  made  in  2,  3,  4,  6,  25  and  35-horse  power.     Horizontal  (portable 
and  stationary)  engines,  made  in  1,  1%,  2#,  4,  6,  8,  10,  12,  15,  20,  25  and  50-horse  power. 

Pumping,  spraying  and  sawing  outfits;  IHC 
oil  tractors  from  12  to  60-horse  power. 

The  illustration  on  this  page  shows  an  I  H  C 
feed  grinder  being  operated  by  the  engine  of  an 
I  H  C  motor  hay  press.  The  power  bed  and  bale 
chamber  of  the  press  have  been  disconnected. 
The  extra  axle  and  wheels  have  been  attached  to 
the  rear  end  of  the  power  bed  and  the  feed  grinder 
has  been  set  up  on  the  power  bed  just  as  it  would 
be  set  up  on  a  barn  floor.  This  engine  may  be 
used  for  operating  many  other  machines,  such  as 
corn  shellers,  wood  saws,  concrete  mixers,  etc.
